I have used 303 Protectant for 30 years. The best there is for interior vinyl and even smooth leathers. All that I have ever used on the vinyl and leather seat covers in my 300 B. All appear as new. Only product used for same in all my cars.
Also excellent for tires. None of that shiny, greasy, plastic looking look of the majority of so called tire protectsnts that are foisted upon us by a majority of too many vendors. .
My leftover supply of Armor All,,,yes I too must plead guilty,,,when I found 303, I sprayed upon the previously invincible crab grass in my lawn. It is yet to return.
Next to detailing clay which I've used for 20 plus years, likely my favorite by a wide margin, detailing product. Try it, you won't go back.
Incidentally there now exists an improved successor to detailing clay that appears will be a real threat to its success.
